Syria has been engulfed in a civil war for over five years that has seen the Syrian regime, led by Bashar al Assad, use deadly force to quell a national uprising inspired by the Arab Spring movement.

The country is currently split among regime-held areas, rebel-held areas and Daesh-controlled areas.

Over 5 million Syrians have fled their country since the conflict erupted in 2011. The International Organization for Migration (IOM) said about 21 percent of Syrians were living outside of their country by the end of 2015.
